Description
When hydraulic fluid starts weeping around fittings or you’re losing pressure in your three-point hitch, worn O-rings are usually the culprit. This 5-1/2 inch inside diameter O-ring handles the big connections on larger tractors and equipment where standard seals just won’t cut it. Made from durable Buna-N rubber that resists the oils, fuels, and hydraulic fluids your equipment depends on, these seals restore tight connections and keep systems running at full pressure.
What You’re Getting
- Ten O-rings per package – enough for multiple repairs or to keep spares on hand
- 70 durometer Buna-N rubber construction that handles farm chemicals and temperature swings
- Precise 5-1/2 inch ID x 6 inch OD x 1/4 inch wide dimensions for proper sealing
- Versatile sealing solution for hydraulics, plumbing, irrigation, and automotive applications
Built for Real Farm Work
These larger O-rings fit the substantial hydraulic components found on mid-size and larger tractors, combines, and heavy equipment. Whether you’re resealing hydraulic cylinders on your loader, fixing leaks in implement couplers, or maintaining irrigation systems, this size handles connections where smaller seals would fail under pressure.
Made to Last
Buna-N rubber stands up to the harsh conditions farm equipment faces daily. It resists swelling from hydraulic oil, won’t crack from temperature changes, and maintains its sealing properties through thousands of pressure cycles. The 70 durometer hardness provides the right balance of flexibility for sealing and firmness for durability.
Good to Know
Always clean sealing surfaces thoroughly before installing new O-rings – dirt or old rubber fragments will cause leaks. A thin coat of hydraulic fluid helps O-rings slide into place without rolling or tearing. Replace O-rings whenever you disconnect hydraulic fittings – reusing old ones almost always leads to comeback leaks.
